I don't want to start another war of words with N_grimm on this, but your post brought me back to the question of, just what exactly is the Burkhardt family tradition regarding Grimms? If I saw all of the books documenting the supposed enemy, the weapons, and poisons all hidden in a trailer so one could easily travel without leaving a trail, I'd be thinking of two words; serial killer. I would say Nick tries to avoid that somewhat, but his internal battle is not one of a Grimm trying to overcome a bloody past, but instead a person who avoids the reality of what he's about to do by virtue of some random statement. Hence, the "I owe it to her" about Marie. There is obsession there, and I think some greed too. He doesn't give a thought about the risks his friends are taking in making it happen for him.
You've made comments about Adalind and her inability to get it right, so to speak, when she's casting her spells. I can see Nick in the same way. He's not casting spells, of course, but he's had his share or disastrous and catastrophic results as a Grimm. Both of them managed to lose their powers and then gain them back. Yet, they did not change and grow and learn from their mistakes.

The best way to frustrate a cyberbully is to ignore him.
